Business Context

The IT project we carried out was focused on developing an intelligent multimedia system for modern connected vehicles, with entertainment capabilities. Andersen delivered:

  • Home screen with widgets;
  • Vehicle signals emulation (Windows);
  • Vehicle settings;
  • Connectivity settings;
  • Audio;
  • XSM Radio and weather services;
  • Phoning functionality.


This project aimed to develop a car multimedia system centered around a single display, which had been initiated nine months prior to the hardware Standard Operating Procedure (SOP) phase. The scope encompassed redesigning the user interface, utilizing Qt/QML, and ensuring consistent visual branding across all car models. Andersen's team focused on several key tasks, including crafting a robust software architecture, establishing a vehicle communication framework (including simulation tools), and developing essential applications using Qt/QML on top of the QNX platform.
